I IORSESHOE'-CALK..

. To all whom it may concern:

Be it known that I, FnAngois BOUDUBAN, a citizen of the United States of America, residing at Highland Park, in the county of WVayne and State of Michigan, have invented certain new andv useful Improvements in Horseshoe-Calks, of which the following is a specification, reference being had therein to the accompanying drawings.

This invention relates to .horse shoes, and the objects of my invention are, first, to provide a horse shoe with detachable toe and .heel calks that can be easily removed, sharpened, and renewed when broken; second, to rovide a horse shoe with detachable calks that are held in place by malleable lugs forming part of the calks and thereby obiating the necessity of using screws, wedges or devices liable to become accidentally displaced during the use of the shoe, and third, to furnish the shoe with strong and durable calks that will prevent an animal from slipping upon smooth and slippery surfaces.

The above and other objects are attained by a mechanical construction that will be hereinafter specifically described and then claimed, and reference will now be had to the drawing, wherein Figure 1 is a perspective view of an inverted horse shoe provided with detachable calks in accordance with this invention; Fig. 2 is an enlarged cross sectional View of the heel of a shoe illustrating a heel calk; Fig. 3 is a longitudinal sectional view of the same; Fig. l is across sectional view taken on the line IV-IV of Fig. 3; Fig. 5 is a side elevation of a detached heel calk, and Fig. 6 is a perspective view of a heel portion of a shoe illustrating amodified form of heel calk.

In the drawing,'1 denotes a horse shoe having the ordinary groove 2 and openings 3 to accommodate nails for securing the shoe to the hoof of an animal. The toe of the shoe has a toe piece 4 and a depending transverse socket member 5, while the heels of the shoe have depending longitudinal socket members 6. The members 5 and 6 are identical in construction and the calks mounted therein approximately so, therefore I deem it only necessary to describe one of the heel portions of the shoe.

The socket member 6 has a longitudinal dove-tailed groove 7 terminating in proximity to the rear end of the member whereby one end of the groove will be closed. The

bottom of the groove is in a plane with the I bottom side of the shoe 1 and said groove 1s adapted to. receive a longitudinal tongue 8 carried by a. transverse heel calk 9. The

calk 9 is of a greater width than the tongue 8 whereby said. calk will engage the socket member, as best shown in Fig. 2, thus rebetween the calk and the tongue of stresses and strains especially when an animal has the habit of pounding the feet.

The dove-tail tongue 8 has a forwardly extending malleable lug 10 in a plane with the bottom of said tongue and the forward end of said lug has the bottom side thereof cut away, as at 11, to provide a recess adapted to receive the end of a tool or implement, as will hereinafter appear.

The shoe 1, at the forward end of the socket member 6, has a pocket 12 to receive the malleable lug 10 of the tongue 8. The lug 10 is adapted to be bent and driven into the pocket 12 and said pocket provides end shoulders 13 against which the forward end of the lug abuts and consequently cannot become longitudinally displaced. With the lug 10 bent into the pocket 12 the tongue 8 and the calk 9 are held in position without any additional fastening means. Provision is made for bending the lug 10 out of the pocket 12 by providing the shoe 1 with a small groove 14 in communication with the pocket, said groove permitting of the end of a suitable tool or instrument being inserted under the end of the lug 10, within the recess 11, whereby the end of the lug can be pried out of the pocket and the tongue 8 removed from the socket member 6.

The toe calk is designated 15 and the lug 16 thereof is sli htly curved to conform to the curvature o the shoe 1 at the toe portion thereof.

In Fig. 6 of the drawing there is illustrated slight modification of the invention wherein a tongue 17 is provided with a longitudinal heel calk 18 instead of a transverse calk, and the tongue 17 is held by a malleable. lug 19.

WVhile in the drawing there are illustrated the preferred embodiments of my invention, it is to be understood that the structural. elements are susceptible to such variations and modifications as fall within the scope of the appended claim.

What I claim is:

The combination of a horse shoe,

depending heel socket members carried thereby and ed to be bent into a ocket to engage the having the inner ends thereof merging into shoulders thereof to hold said tongue against the bottom of the shoe and provided With longitudinal displacement in a socket memdove-tailed grooves with the bottom of each ber, said lug being flush with the inner end 5 groove in the same plane as the bottom of of the'socket member and the bottom of the shoe and the outer end of each groove said shoe having the end thereofprovided closed by said socket members, said shoe With an under cut recess adapted to register having a pocket formed therein at the inner With-the, inner end of the groove of said end of each socket member With the outer shoe, the undercut recess of said lug being 10 end of said pocket merging into the bottom the entire Width thereof whereby a suitable oi the dove-tail groove and a groove in comtool can be inserted under the end of said munication With the inner end of each lug Within said groove to pry the same from pocket, said pocket providing shoulders at its pocket.
